Abstract
A catalytic component having the formula (MXa) (MgX2)b (RMgX)c (MHgX)d wherein M is a metal selected from group VI B and group V B of the Periodic Classification, X is a halogen, R is a hydrocarbon radical, 2</=a </=3.5, 1</=b</=30, 1</=c</=8 and 0</=d</=10 is prepared by reducing a metallic halide of the metal M, the valency of said metal being 4 if a metal of group IV B is concerned and 4 or 5 if a metal of group V B is concerned, by means of at least one organomagnesium compound having the formula RMgX, the said organomagnesium compound being used in the solid state and reduction of the metallic halide being carried out under a pressure lower than or equal to atmospheric pressure and at a temperature lower than the decomposition point of said organomagnesium compound under the pressure concerned but at least 10 DEG higher than the boiling point or sublimation point of the metallic halide under the pressure concerned.
